Associating contacts to SIM numbers


This is my first post here, as I'm a pretty new (and happy!) Android user. So...

Hello, everyone! :)

I own an Alcatel OT-918D, dual sim, and I'm quite satisfied with it.
Only issue: I can't find a way to associate contact's numbers to my SIM cards.

For example, if a certain contact has 2 phones, I'd like to associate one phone with one SIM card, and the other phone with the other card, such that when I call or text one of the two number, the proper sim card is used.

How can I achieve that? I can replace or use another dialer application/contacts management if necessary... Only thing: I'd like to keep my contacts synced with GMail Contacts (so that Gmail and phone are 1:1).

Thanks in advance for any help :)
